There'a a lot of log data in comment #4 and a few possible problems: 1. The kernel is crashing repeatedly in wifi-related code:
Jan 10 16:17:19 Keschdeichel kernel: wlp4s0: Failed check-sdata-in- driver check, flags: 0x0 Please try downgrading to the official bionic kernel (v4.15) and/or avoid using wifi for a while. 2. There are some errors from unsupported gnome-shell extensions. Please uninstall extensions such as '[email protected]'. Disabling them isn't enough. 3. It looks like you ran out of disk space at one point. Please check that. 4. Near the end (the hang) a couple of components mention I/O errors: Jan 25 07:08:30 Keschdeichel gsd-power[4979]: Error setting property 'PowerSaveMode' on interface org.gnome.Mutter.DisplayConfig: Timeout was reached (g-io-error-quark, 24) Jan 25 07:09:33 Keschdeichel gvfsd[4865]: Error 2: Error 02ff: PTP I/O Error which may indicate a disk is starting to fail. Or it may be unrelated to disks completely. 5. Near the end (the hang) your CPU started to overheat: Jan 25 07:09:36 Keschdeichel kernel: CPU2: Core temperature above threshold, cpu clock throttled (total events = 3993) Jan 25 07:09:36 Keschdeichel kernel: CPU6: Core temperature above threshold, cpu clock throttled (total events = 3993) Jan 25 07:09:36 Keschdeichel kernel: CPU2: Package temperature above threshold, cpu clock throttled (total events = 13593) Jan 25 07:09:36 Keschdeichel kernel: CPU6: Package temperature above threshold, cpu clock throttled (total events = 13593) Jan 25 07:09:36 Keschdeichel kernel: CPU4: Package temperature above threshold, cpu clock throttled (total events = 13593) Jan 25 07:09:36 Keschdeichel kernel: CPU0: Package temperature above threshold, cpu clock throttled (total events = 13593) Jan 25 07:09:36 Keschdeichel kernel: CPU1: Package temperature above threshold, cpu clock throttled (total events = 13592) Jan 25 07:09:36 Keschdeichel kernel: CPU5: Package temperature above threshold, cpu clock throttled (total events = 13593) Jan 25 07:09:36 Keschdeichel kernel: CPU7: Package temperature above threshold, cpu clock throttled (total events = 13593) Jan 25 07:09:36 Keschdeichel kernel: CPU3: Package temperature above threshold, cpu clock throttled (total events = 13593) Please also follow these instructions to check for possible crashes: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment ** Changed in: gdm3 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1813248 Title: Hang at screen unlock (gdm / 18.04) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1813248/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
